Avid's BB7 is more powerful and easier to set up than any mechanical disc system that's ever gone before, surpassing the performance of it's little brother the BB5 by providing dual sided pad adjustment via the large red dial on each side, this addition allows the rider to fine tune the distance between the rotor and pad contact surface, maintaining maximum stopping power as the pads wear. Precision ball bearing actuation, 2 piece forged body ensures any rider can tune the feel of the brakes to suit their preferences. Whilst the Tri-Align caliper positioning system allows the caliper to be aligned perfectly in 3 easy steps; simply loosen the caliper mounting bolts, pull the brake lever tight and then with the lever held re-tighten the mounting bolts, it's that easy.Fitment: IS (With Supplied Adapter), Post MountPads: OrganicWeight: 329g
